74LCXP16245MTDX

Overview

The 74LCXP16245MTDX is a 16-bit bus transceiver manufactured by onsemi, designed for low-voltage applications. It operates within a supply voltage range of 2 V to 3.6 V and features three-state outputs. The device supports bidirectional data transfer with a propagation delay of 5.2 ns. It accommodates LVTTL or TTL input levels while providing LVCMOS output levels. Packaged in a TSSOP-48 format, it offers a low-level output current of 24 mA and a high-level output current of -24 mA. The component functions as a non-inverting transceiver with bus hold capabilities.

Feature Summary

• Provides 16-bit bidirectional data transmission capability between two buses.
• Integrates bus hold functionality to maintain stable logic states during idle periods.
• Supports mixed voltage operation by accepting LVTTL/TTL inputs with LVCMOS outputs.

Applications

• High-density data bus architectures requiring 16-bit width.
• Systems utilizing mixed voltage logic families such as LVTTL and LVCMOS.
• Embedded controllers managing bidirectional peripheral communication.

Procurement Notes

Verify the specific suffix MTDX against official onsemi documentation to confirm package type and reel specifications. Confirm that the LCXP series designation aligns with the required bus hold features for your design. Check current lifecycle status as this component may be subject to obsolescence notices from the manufacturer.

Selection Notes

Select this component when a 16-bit wide interface is necessary alongside bus hold stability. Ensure the system power supply remains within the 2 V to 3.6 V operational window. Verify that the TSSOP-48 package dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to the LCXP family of bus transceivers, which are optimized for low-voltage CMOS technology. The LCXP series distinguishes itself through integrated bus hold features, enhancing signal integrity in complex digital systems compared to standard variants lacking this function.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may lack the specific bus hold feature or exact pin compatibility required for direct replacement without schematic modification.
